Bacillus subtitles
• Bacillus subtilis is considered the best studied gram positive bacteria.
• It is used around the world to make different types of fermented food.
• When conditions are unfavorable it can go dormant by forming an endospore where it can withstand harsh conditions.
• Because it is a spore former, when it is not in a spore it is referred to as a “vegetative cell”.
• Bacillus subtilis is known to produce a lot of extracellular enzymes such as amylases and proteases.
• This tolerance to harsh conditions as well as other positive benefits they have in the gut, is why Bacillus subtilis and other members of its genus are often used as probiotics.

What Microbe is this?

Salmonella sp.

• Salmonella enterica is known to be more of a concern in warm-blooded animals around the world, while Salmonella bongori is typically only present in cold-blooded animals such as reptiles.
• There are 6 subspecies and over 2600 serotypes. Enteritidis, Typhimurium, Kentucky are all examples of Salmonella serotypes.
